Having never played or heard of the game before this, I am hesitant to edit the page. However, I played the game for a few hours with a large group of kids from 5-15 years old, and we found that if you allow bugs to be squashed if they're adjacent to a fortress, it leads to a kind of contagion where nobody places any new bugs after the first contact is established, and all chains of bugs are just squashed all the way back to the home base. Restricting the squash operation to only situations where a friendly bug is adjacent to an enemy bug solved the problem and led to much more interesting play. I put a note on the talk page for the wikipedia draft, but perhaps someone who has played the game before can comment on this?
